Hello all. I'm planning out an 8-string bass and I'm exploring my options for the pickup and preamp. I want a single MM style pickup. Right now I'm looking at Bartonlini and Seymour Duncan because they are blade style. Preamp is a different story. My top three choices are Demeter, 3-band Bartolini or Seymour Dunan. Any thoughts or experiences would be greatly appreciated.... Thanks!
